Summary The kinetics of the reaction between NCS− and the diprotonated forms of [ReO2(CN)4]3− have been studied in theca. 1 to 3 pH range. This study showed that the diprotonated form [ReO(OH2)(CN)4]−1 is the only reactive species and that only the aqua ligand is substituted by the thiocyanate ions according to the following reaction: $$[ReO(OH_2 )(CN)_4 ]^{1 - } + NCS - [\operatorname{Re} O(NCS)(CN)_4 ]^{2 - } + H_2 O$$ The k1 and k−1 values are 3.48(4)×10−3 M−1 s−1 and −3(2)×10−5 s−1 respectively at 25°C. A dissociative activated substitution process is proposed.
